What are some interesting plot ideas for 'Peter and Valkyrie MCU fanfiction'?

Maybe in the fanfiction, MCU Peter is on a mission when he accidentally stumbles into a portal and ends up in the world of another Peter. They start comparing their lives, like how different their love interests are. MCU Peter could learn some old - school web - slinging techniques from the other Peter, and they end up having to fight a villain that threatens both of their worlds, leading to a great team - up.

A new character could be created as the main antagonist. For example, a powerful sorcerer from another dimension who wants to steal the powers of both Peter and Valkyrie. This villain could be after the spider - powers and Valkyrie's Asgardian strength to increase his own power and take over the MCU universe.

Another plot could involve Nora somehow getting access to Naruto's chakra system. This could lead to her developing new powers similar to Naruto's. They might train together, with Nora teaching Naruto about the different Dust types in her world while Naruto shows her more advanced chakra control techniques. Their combined skills could then be used to face a powerful common enemy.

One idea could be a crossover where Naruto characters are transported to the Valkyrie universe. They could team up with the Valkyries to fight a common enemy, like an ancient evil that threatens both worlds. Naruto's skills in ninjutsu would be a great addition to the Valkyries' combat capabilities.

One idea could be exploring Wendy's life back in London after her adventures in Neverland. Maybe she's having a hard time adjusting and misses Peter terribly. Another could be a story where Peter brings some of the Lost Boys to London for a visit and the chaos that ensues. A third idea might be a tale where Wendy's younger siblings grow up and start to doubt the existence of Peter Pan, but Wendy has to convince them he's real.

A plot idea might involve a time when the magic of the starstuff is fading in Neverland. Peter has to go on a quest to find the source of the starstuff and restore its power. Along the way, he meets new friends and foes, and has to use his wits and flying skills to overcome obstacles. This could also lead to him learning more about his own past and connection to the starstuff.

One idea could be exploring Peter's life before he became the famous Peter Pan. Maybe he had a best friend in the orphanage who was left behind when he went to Neverland. Another plot could be about the origin of the starstuff and how it affects different characters in ways not shown in the original. For example, a minor character could gain some special powers from a small amount of starstuff and use it for good or bad.

Another interesting plot could be a redemption arc for Peter Pettigrew. What if he had a change of heart during the events of the books and tried to make amends? Writers could show how the other characters react to his attempts at redemption, whether they believe him or not. It could also involve him using his skills in a positive way to help defeat Voldemort in the end. This would be a complex and engaging plot as it goes against the typical view of him as a traitor.

One idea could be that Peter and Quagmire start a business together. They might open a bar where all sorts of crazy things happen. For example, they could have themed nights inspired by their wildest adventures in Quahog. Another plot could be that they get lost in the woods while on a hunting trip and have to rely on each other's skills to survive. Maybe they find a mysterious cave and discover something that changes their friendship forever.

One interesting storyline could be Peter Parker trying to balance his superhero duties with his relationships in the harem. For example, he has to keep his identity a secret from some of the girls while still being there for them. Another could be the different dynamics between the characters in the harem, like a love - hate relationship with one of them.
